I can get the Visual Studio Integrated Configuration Editor to bomb everytime I do the following:

1) Create New Console Application Project
2) Add app.config
3) Right-Click on app.config and choose to open with Ent Lib Editor
4) It asks to close app.config and re-open with new editor...

At this point it used to totally close Visual Studio. Now in the Feb 2007 CTP it asks me to debug it.

I debug with a new instance of Visual Studio 2005 and get the following information:

"A buffer overrun has occurred in devenv.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.

For more details please see Help topic 'How to debug Buffer Overrun Issues'."

Breaks on the debuggerhook_dummy = 0 statment at the end.

In addition to Dave's problem, it also seems to bomb if I forget to check-out app.config from Perforce.

Thanks guys - we'll look into this.

In addition, if you open the editor, close it, edit the raw app.config, and then open the editor again, the changes are not reflected. This was in the jan-CTP, I have not tested the feb-CTP.
